Gypsum powder production lines in Europe are designed to process raw gypsum rock into fine powder, which is used in various industries such as construction, agriculture, and manufacturing. The production process typically involves several stages, including crushing, grinding, calcination, and packaging. Here’s an overview of the key components and steps involved in a gypsum powder production line:
1. Raw Material Preparation
– Mining: Gypsum rock is extracted from quarries or mines.
– Crushing: The raw gypsum rock is crushed into smaller particles using crushers.

2. Grinding
– The crushed gypsum is then ground into a fine powder using grinding mills. This step ensures the material reaches the desired fineness for further processing.
3. Calcination
– The ground gypsum powder is heated in a calciner to remove the water content (dehydration). This process converts the gypsum (CaSO₄·2H₂O) into calcium sulfate hemihydrate (CaSO₄·0.5H₂O), also known as stucco or plaster of Paris.
– Calcination can be done using different types of kilns, such as rotary kilns or flash calciners.
4. Cooling
– After calcination, the hot gypsum powder is cooled down to a suitable temperature for storage and packaging.
5. Packaging
– The final gypsum powde
s packaged in bags or bulk containers for distribution and sale.
Key Equipment in a Gypsum Powder Production Line
– Crushers: For reducing the size of raw gypsum rock.
– Grinding Mills: For producing fine gypsum powder.
– Calciners: For heating and dehydrating the gypsum.
– Cooling Systems: For cooling the calcined gypsum.
– Packaging Machines: For packing the final product.
